Description

Technical Field

[0001] This application relates to the technical field of cookware, and in particular to a combustion system and cookware. Background Art

[0002] Currently, most common cookware uses an open-flame heating method, that is, the bottom of the pot is directly heated by the flame to achieve the cooking purpose. This method is widely used in household kitchens and the catering industry and is generally welcomed because of its simple operation and low cost. However, under the requirements of modern high efficiency and energy conservation, the traditional open-flame heating method has gradually shown its limitations. With the rising energy prices and the increasing awareness of environmental protection, improving energy utilization efficiency has become an urgent problem to be solved.

[0003] To improve energy utilization efficiency, various methods are usually adopted to optimize the combustion process. For example, heat-conducting components such as a fire guide groove or a convex structure can be provided at the bottom of the pot to increase the contact area between the pot body and the flame, so as to absorb heat more effectively. Another common method is to improve the design of the burner so that it can generate a more uniform and efficient flame and reduce heat loss. In addition, the oxygen supply can be controlled by adjusting the size of the air damper to make the fuel burn more fully and further improve the energy conversion rate.

[0004] Although the above measures can improve energy utilization efficiency to a certain extent, there are still obvious deficiencies in actual applications. Especially for the traditional open-flame heating method, the flame can only heat the bottom of the pot body, and the heated area is limited, resulting in a large amount of heat that cannot be effectively transferred to the food and instead is lost due to heat exchange with the air. This phenomenon not only wastes precious energy resources but also causes the ambient temperature around the pot body to rise rapidly, affecting the user experience. Therefore, how to significantly improve energy utilization efficiency while maintaining the convenience of existing equipment is an urgent technical problem to be solved currently. Summary of the Invention

[0005] This application provides a combustion system and cookware with high combustion efficiency and energy utilization efficiency.

[0006] In a first aspect, a combustion system provided by this application adopts the following technical solution: A combustion system includes a combustion tube, an exhaust pipe, a mixer, and a fuel nozzle; The mixer is arranged outside the combustion tube. The mixer has a first air inlet and a fuel outlet, and the fuel outlet is communicated with the combustion tube; The fuel nozzle is arranged on the mixer and is used to inject fuel into the mixer, and the fuel and air enter the combustion tube through the mixer; The exhaust pipe is communicated with the combustion tube; The combustion tube is placed inside the container to heat the substances inside the container.

[0007] By adopting the above technical solutions, on the one hand, the fuel and air are fully mixed in the mixer and then sprayed into the combustion tube after ignition, thus improving the combustion efficiency of the fuel in the combustion tube. The combustion tube is placed inside the container and immersed in substances such as water and oil, and directly heats the water, oil and other substances in the container through heat exchange. Compared with the heating method of heating the bottom of the pot, the heat loss is effectively reduced and the energy utilization rate is improved. The design of the exhaust pipe enables the exhausted gas after combustion to be discharged smoothly, ensuring the stable operation of the system.

[0008] Preferably, the mixer includes a pipe body. One end of the pipe body is set as a fuel outlet and is fixedly connected and communicated with the combustion tube. The fuel nozzle is arranged at the other end of the pipe body and is placed inside the mixer, and the fuel nozzle is arranged towards the fuel outlet; the first air inlet is opened on the side wall of the pipe body.

[0009] By adopting the above technical solutions, the fuel nozzle is arranged at the other end of the pipe body and is arranged towards the fuel outlet. Therefore, when the fuel is sprayed out, due to the relatively high flow rate, a low-pressure area is formed at the first air inlet, sucking air from the first air inlet into the mixer and mixing the air with the fuel, thereby improving the thermal efficiency and stability of the combustion system.

[0010] Preferably, an auxiliary air hole is arranged at the end of the pipe body where the fuel nozzle is located, and the auxiliary air hole is arranged at an interval from the first air inlet.

[0011] By adopting the above technical solutions, the setting of the auxiliary air hole can increase the air intake. Specifically, after the fuel nozzle sprays fuel in the mixer, the mixture of fuel and air enters the combustion tube from the mixer. The air flow rate in the mixer is relatively high and the air pressure is relatively low, enabling air to enter the mixer from the first air inlet and the auxiliary air hole. And arranging the auxiliary air hole at an interval from the first air inlet can prevent the air flow in the auxiliary air hole from affecting the air flow in the first air inlet, ensuring the full mixing of fuel and air flow.

[0012] Preferably, the fuel nozzle includes a spray pipe and a nozzle. The nozzle is located at one end of the spray pipe and faces the other end of the spray pipe, and the spray pipe is arranged towards the inside of the mixer; a second air inlet is opened on the side wall of the spray pipe, and the second air inlet is arranged towards the auxiliary air hole.

[0013] By adopting the above technical solutions, after the fuel is sprayed out from the nozzle, air will enter the second air inlet from the auxiliary air hole and be preliminarily mixed with the air in the spray pipe. Subsequently, the fuel is further mixed with the air in the mixer for the second time, thus effectively increasing the oxygen content and ensuring the full combustion of the fuel in the combustion tube.

[0014] Preferably, the combustion tube is provided as a straight tube or a bent tube; the mixer is arranged at one end of the combustion tube, and the exhaust pipe is arranged at the other end of the combustion tube.

[0015] By adopting the above technical solution, the combustion tube can be set into various different straight tube or bent tube shapes, which can adapt to cookware of different shapes. In addition, when the combustion tube is set as a straight tube, the flow efficiency of the gas in the combustion tube can be improved; while when the combustion tube is set as a bent tube, the surface area of the combustion tube can be increased, the combustion space and the heat exchange area can be enlarged, and the energy utilization rate can be further improved.

[0016] Preferably, the end of the combustion tube far from the mixer is closed. The exhaust pipe is arranged in parallel with the combustion tube, and the exhaust pipe is connected and communicated with the combustion tube through a connecting pipe; the middle position of the exhaust pipe is inside the container, and the end extends outside the container and serves as an exhaust port.

[0017] By adopting the above technical solution, after the fuel burns sufficiently in the combustion tube, the generated waste gas enters the exhaust pipe through the connecting pipe. Since the waste gas still has a relatively high heat, the exhaust pipe can also heat the substances in the container, thereby realizing the full utilization of the waste gas energy.

[0018] Preferably, the connecting pipe is inclined relative to both the combustion tube and the exhaust pipe, and the end of the connecting pipe connected to the combustion tube is arranged far from the exhaust port, and the end of the connecting pipe connected to the exhaust pipe is arranged close to the exhaust port.

[0019] By adopting the above technical solution, through the inclined connecting pipe, the connecting pipe can play a guiding role in the waste gas, thereby optimizing the gas flow path between the combustion tube and the exhaust pipe, enabling the waste gas to flow into the exhaust pipe from the combustion tube in time and being discharged from the exhaust port, and reducing the flow resistance of the waste gas.

[0020] Preferably, the exhaust pipe also has an air inlet, and the air inlet and the exhaust port are respectively located at both ends of the exhaust pipe.

[0021] By adopting the above technical solution, the waste gas will be discharged from the exhaust port under the guiding action of the connecting pipe. At the same time, since the gas flow rate in the exhaust pipe is relatively fast, and the inside of the exhaust pipe is an open environment with a relatively high temperature, the air pressure inside the exhaust pipe is also relatively low, and the outside air of the exhaust pipe can enter from the air inlet. On the one hand, it can increase the oxygen content inside the exhaust pipe and the combustion tube, improving the combustion sufficiency. On the other hand, it can also improve the gas flow efficiency inside the exhaust pipe and assist in exhausting the smoke.

[0022] Preferably, a plurality of combustion chambers are provided on the combustion tube, and the plurality of combustion chambers are evenly distributed along the length direction of the combustion tube; the inner diameter of the combustion chamber is larger than the inner diameter of the combustion tube, and the plurality of exhaust pipes correspond to the plurality of combustion chambers one by one, and the exhaust pipe is connected to the combustion chamber.

[0023] By adopting the above technical solution, the fuel sequentially enters each combustion chamber through the combustion tube. On the one hand, by increasing the inner diameter of the combustion chamber, a larger combustion space is provided inside the combustion chamber, the residence time of the fuel is increased, thereby improving the sufficiency of fuel combustion, and it is not easy for the fuel to be discharged through the exhaust pipe without being fully burned. On the other hand, the combustion chamber has a large surface area, which can improve the heat exchange efficiency. In addition, through the connection between the connecting pipe and the combustion chamber, the exhaust efficiency can be improved, and after the oxygen-containing air enters the exhaust pipe, part of the fuel that is not fully burned can continue to burn, thereby improving the utilization efficiency of the fuel.

[0024] On the other hand, the present application provides a cooking utensil, adopting the following technical solution: A cooking utensil includes a pot body, a water filtering basket provided inside the pot body, and a combustion system; The combustion tube is located inside the pot body and between the pot body and the water filtering basket; the end of the combustion tube passes through the pot body and extends to the outside of the pot body, and the connection between the combustion tube and the pot body is sealed; the mixer is located outside the pot body.

[0025] By adopting the above technical solution, the combustion system of the cooking utensil can efficiently heat the substances in the pot body. Specifically: the combustion tube is placed inside the pot body, so that the heat can be directly transferred to the substances to be heated, reducing the loss of heat energy. The design of the mixer ensures that the fuel and air are fully mixed before entering the combustion tube, improving the combustion efficiency and reducing the emission of unburned fuel.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects: 1. The fuel and air are fully premixed in the mixer and then enter the combustion tube, improving the combustion efficiency of the fuel, and the combustion system can efficiently heat the substances in the pot body directly, reducing the heat loss and improving the energy utilization rate; 2. The setting of the mixer and the fuel nozzle can make the fuel and air fully mixed, thereby improving the combustion efficiency and further enhancing the combustion effect; 3. The exhaust pipe and the combustion tube are arranged in parallel, which can utilize the heat in the exhaust pipe, thereby effectively improving the energy utilization rate; 4. The setting of the air inlet on the exhaust pipe can, on the one hand, increase the oxygen content inside the exhaust pipe and the combustion tube, improve the combustion sufficiency, and on the other hand, also improve the gas flow efficiency inside the exhaust pipe to assist in exhausting.

Detailed Description of the Embodiments

[0030] The following further elaborates on the present invention in conjunction with the attached Figures 1-10 drawings.

[0031] The inventors of the present application found that most existing cookware uses an open-flame heating method. Although it is easy to operate and has a low cost, there are problems such as large heat loss and low energy utilization rate. For this reason, the present application mainly adopts a combustion system including a combustion tube 1, an exhaust pipe 2, a mixer 3 and a fuel nozzle 4. After the fuel and air are fully premixed in the mixer 3, they enter the combustion tube 1 to be ignited, directly heating the substances inside the container, thereby reducing heat dissipation and significantly improving energy utilization rate.

[0032] Embodiment 1 An embodiment of the present application provides a combustion system. Refer to Figure 1 and Figure 2 , which specifically includes a combustion tube 1, an exhaust pipe 2, a mixer 3, and a fuel nozzle 4. Among them, the mixer 3 is connected to the combustion tube 1 and mixes fuel and air and then sends them into the combustion tube 1. The exhaust pipe 2 is communicated with the combustion tube 1 for discharging waste gas. The combustion tube 1 is placed inside a container to heat the substances in the container, achieving the effect of improving energy utilization efficiency.

[0033] Specifically, the mixer 3 includes a tube body 31. One end of the tube body 31 is set as a fuel outlet and is fixedly connected and communicated with the combustion tube 1, and the other end is provided with a fuel nozzle 4. The fuel nozzle 4 faces the fuel outlet. A first air inlet 32 is opened on the side wall of the tube body 31. When the fuel is ejected, due to the relatively high flow rate, a low-pressure area is formed at the first air inlet 32, sucking air into the interior of the mixer 3 through the first air inlet 32 and mixing the air with the fuel, thereby improving the thermal efficiency and stability of the combustion system.

[0034] The tube body 31 can be made of high-temperature resistant stainless steel material, having good strength and corrosion resistance, and can be connected to the combustion tube 1 by welding or threaded connection.

[0035] In addition, auxiliary air holes 33 are provided on the tube body 31, and the auxiliary air holes 33 are arranged at intervals with the first air inlet 32. For example, the number of auxiliary air holes 33 can be set to multiple according to actual needs and distributed around the tube body 31 to provide more fresh air to participate in the combustion process. Such a design helps to increase the oxygen supply, ensure full combustion of the fuel, and thus improve the overall combustion efficiency.

[0036] Refer to Figure 2 and Figure 3 , further, the fuel nozzle 4 is composed of a nozzle tube 41 and a nozzle 42. The nozzle 42 is located at one end of the nozzle tube 41 and faces the other end of the nozzle tube 41. The nozzle 42 can be connected to an external fuel bottle to spray fuel into the mixer 3. The nozzle tube 41 faces the interior of the mixer 3. A second air inlet 43 is opened on the side wall of the nozzle tube 41, and the second air inlet 43 faces the auxiliary air holes 33. The nozzle tube 41 can be made of stainless steel material, having good wear resistance and thermal conductivity; the nozzle 42 can be made of brass material, having excellent high-temperature resistance and oxidation resistance. When the nozzle 42 sprays fuel, a negative pressure area will be formed in the nozzle tube 41, prompting air to enter the second air inlet 43 through the auxiliary air holes 33, and being preliminarily mixed in the nozzle tube 41, and then mixed with the air from the first air inlet 32 again. Finally, the formed mixed gas enters the combustion tube 1 through the fuel outlet.

[0037] Further, the combustion tube 1 can be set in the form of a straight tube or a bent tube. If a straight tube structure is selected, it is beneficial to simplify the processing technology and reduce the production cost; while when a bent tube design is adopted, not only can the combustion space be increased, but also the heat exchange area can be expanded, thereby further optimizing the energy conversion effect. For example, the bent part can be in an arc shape or other suitable shapes, and can be flexibly adjusted according to the specifications of the target cookware.

[0038] The exhaust pipe 2 is arranged at one end of the combustion tube 1 far from the mixer 3 and is fixedly connected to the combustion tube 1 by fixing means such as welding or screwing. The waste gas generated by the combustion of the fuel in the combustion tube 1 will be discharged through the exhaust pipe 2.

[0039] Optionally, in order to further optimize the combustion effect, a vortex generator is added inside the mixer 3 to make the fuel and air form a swirl before entering the combustion tube 1, improving the mixing uniformity. The vortex generator can be a group of spiral blades or a plate-like structure with inclined holes, and the specific form can be selected according to actual needs. In addition, a filter screen is added to the air inlet 23 on the exhaust pipe 2 to prevent foreign impurities from entering the combustion system and extend the service life.

[0040] Referring to Figure 4 and Figure 5 This application embodiment also discloses a cookware, which includes a support frame 7, a pot body 5, a water filter basket 6 arranged inside the pot body 5, and the above combustion system. Specifically, the pot body 5 is fixed on the top of the support frame 7, and a lid 73 that can be rotated and opened is also provided on the top of the pot body 5. The water filter basket 6 is placed inside the pot body 5. The pot body 5 is used to hold substances such as water and oil, and the water filter basket 6 can hold food materials to facilitate steaming of the food materials.

[0041] Referring to Figure 6 and Figure 7 The middle position of the combustion tube 1 is located inside the pot body 5 and is placed between the pot body 5 and the water filter basket 6. Both ends of the combustion tube 1 pass through the pot body 5, and the connection between the combustion tube 1 and the pot body 5 is sealed to prevent water leakage. The mixer 3 and the exhaust pipe are both located outside the pot body 5 to ensure normal fuel supply and smoke exhaust.

[0042] Further, a foldable fuel bracket 8 is provided on the support frame 7 for fixing a liquefied gas tank or a gas tank, etc. In addition, in this application, the combustion tube 3 can be set to be single or multiple and arranged side by side on the cookware to achieve different heating powers and meet different heating requirements.

[0043] The bottom of the support frame 7 is provided with feet 71 and pulleys 72 to provide stable support, which can be stably placed in the outdoor environment and has mobility.

[0044] The implementation principle of this embodiment is as follows: integrating the combustion system into the cookware not only simplifies the structure of the device but also improves the convenience of use. The portable design enables users to easily use it outdoors, especially suitable for occasions such as camping and traveling. While retaining the characteristics of high efficiency and energy saving, this embodiment also takes into account the user experience.

[0045] Embodiment Two This application embodiment discloses a combustion system, which is different from Embodiment One in that: the structure of the combustion system is different. Specifically, referring to Figure 8 , the exhaust pipe 2 is arranged in parallel with the combustion pipe 1, and a connecting pipe 21 is arranged between the exhaust pipe 2 and the combustion pipe 1, and both ends of the connecting pipe 21 are fixedly connected to the exhaust pipe 2 and the combustion pipe 1 respectively to realize the connection between the combustion pipe 1 and the exhaust pipe 2. There are multiple connecting pipes 21 and they are evenly distributed along the length direction of the combustion pipe 1.

[0046] One end of the combustion pipe 1 where the mixer 3 is installed is located outside the container, and the other end is closed and located inside the container. The middle part of the exhaust pipe 2 is located inside the container while the end extends outside the container to serve as the exhaust port 22. Therefore, after the fuel burns sufficiently in the combustion pipe 1, the generated waste gas enters the exhaust pipe 2 through the connecting pipe 21. And since the waste gas still has a relatively high heat, the exhaust pipe 2 can also heat the substances in the container, thus realizing the full utilization of the waste gas energy.

[0047] The connecting pipe 21 is arranged obliquely relative to both the combustion pipe 1 and the exhaust pipe 2. One end of the connecting pipe 21 connected to the combustion pipe 1 is arranged away from the exhaust port 22, and one end of the connecting pipe 21 connected to the exhaust pipe 2 is arranged close to the exhaust port 22. The connecting pipe 21 can guide the waste gas, thereby optimizing the air flow path between the combustion pipe 1 and the exhaust pipe 2, enabling the waste gas to flow into the exhaust pipe 2 from the combustion pipe 1 in time and being discharged from the exhaust port 22, reducing the flow resistance of the waste gas.

[0048] The number of exhaust pipes 2 can be single or multiple, and the exhaust pipe 2 can be arranged on the upper side, lower side or horizontal side of the combustion pipe 1.

[0049] Furthermore, since the combustion pipe 1 has a certain length, the oxygen provided only by the mixer 3 is difficult to meet the demand for sufficient fuel combustion. For this reason, the exhaust pipe 2 also has an air inlet 23, and the air inlet 23 and the exhaust port 22 are arranged at both ends. The waste gas will be discharged from the exhaust port 22 under the guiding action of the connecting pipe 21. The gas flow rate in the exhaust pipe 2 is relatively fast, and the inside of the exhaust pipe 2 is an open environment with a relatively high temperature. Therefore, the air pressure inside the exhaust pipe 2 is also relatively low, and the outside air of the exhaust pipe 2 can enter from the air inlet 23. On the one hand, it can increase the oxygen content inside the exhaust pipe 2 and the combustion pipe 1, improving the combustion sufficiency. On the other hand, it can also improve the gas flow efficiency inside the exhaust pipe 2 and assist in exhausting the smoke.

[0050] In addition, a blowing device, such as a blower, can be added at the air inlet 23. The air inlet 23 is connected to the blowing device, so that the blowing device can actively supply air into the exhaust pipe 2, thereby improving the air flow efficiency in the exhaust pipe 2 and ensuring the sufficiency of fuel combustion. However, it should be considered that the air supply speed and air supply volume of the blower should not be too large, otherwise the heat in the exhaust pipe 2 will quickly escape through the exhaust port 22, affecting the thermal efficiency.

[0051] Through the structural design of the exhaust pipe 2 and the combustion pipe 1 in this application, the full utilization of the waste gas energy is realized, thereby improving the thermal efficiency.

[0052] Embodiment Three The embodiment of this application discloses a combustion system, which is different from Embodiment Two in that a plurality of combustion chambers 11 are arranged on the combustion pipe.

[0053] Specifically, referring to Figure 9 , a plurality of combustion chambers 11 are evenly distributed along the length direction of the combustion pipe 1; the inner diameter of the combustion chamber 11 is larger than that of the combustion pipe 1, and a plurality of exhaust pipes 2 correspond to the plurality of combustion chambers 11 one by one, and the exhaust pipe 2 is connected to the combustion chamber 11. The fuel sequentially enters each combustion chamber 11 through the combustion pipe 1. On the one hand, by increasing the inner diameter of the combustion chamber 11, a larger combustion space is provided inside the combustion chamber 11, the residence time of the fuel is increased, thereby improving the sufficiency of fuel combustion, and the fuel is not easily discharged through the exhaust pipe 2 without being fully burned. On the other hand, the combustion chamber 11 has a large surface area, which can improve the heat exchange efficiency. In addition, through the connection of the connecting pipe 21 to the combustion chamber 11, the exhaust efficiency can be improved, and after the oxygen-containing air enters the inside of the exhaust pipe 2, part of the fuel that has not been fully burned can continue to burn, thereby improving the utilization efficiency of the fuel.

[0054] In the embodiment of this application, the combustion chamber 11 can be set to be spherical, square or cylindrical, and can be flexibly designed according to actual needs.

[0055] Embodiment Four The embodiment of this application discloses a combustion system, which is different from Embodiment One in that: the structure of the combustion pipe 1 is different.

[0056] Referring to Figure 10 , specifically, the combustion pipe 1 adopts a U-shaped pipe, and the exhaust pipe 2 and the mixer 3 are located on the same side of the combustion pipe 1. Thus, after the combustion pipe 1 is installed on the pot body 5, a heating circuit can be formed in the pot body 5, which can increase the heating area of the combustion pipe 1, and increase the residence time of the heat, further improving the utilization rate of the heat.

[0057] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
